Guyenne will attempt to colonise up to 5 provinces at the same time, and establish a trading post 50% of the time. Their bonus for colonising provinces next to ones they already control is 10 (well below the default).

Guyenne is a warmonger (having a warmonger value of 75, as opposed to 10).

In choosing provinces to besiege, it is less likely to focus on attacking provinces with high tax values (a value of 3.0 compared to the default of 5.0), it has a slightly larger preference for besieging multiple provinces (0.2 compared to 0.1), is willing to fight further from home (value of 4 compared to default of 0.5), is less likely to defend/liberate their own provinces (1.5 vs 2.0), is more likely to attack provinces with a low Supply value (setting is 2.0 compared to 1.0), and is significantly more aggressive (5.0 vs 1.0).
